Discovering to be a slut

You are Sheyla, a 21 year old virgin and bookworm, you have always regarded yourself to be a little shy, you still don't know but this is about to change, a lot. You don't know what's the reason but from when you woke up this morning you've been feeling hornier than usual, you chose to wear a revealing blouse and jeans shorts today instead of your usual high-neck sweater.

You are having your usual morning shower and unexpectedly you find yourself lightly teasing your clit and it feels *good*, you've always thought that masturbation was a sin, but "How can a sin feel so good?" you think. Hot water runs down your body, over your perky nipples and then down to caress your nether lips. Your arousal is clear: your vulva has reddened, your lips have parted and the wetness between your legs is too sticky to be water.
You finally allow yourself to push a finger inside yourself and hear yourself moaning, you try to be quiet to avoid waking up your roommate, but as you push one more finger in and speed up you can't stop yourself completely. As you get near to climax your roommate asks "Are you ok Sheyla? You are going to miss class if you don't finish up fast", you manage to squeak an "Almost done" as you feel your insides burning and your orgasm.

You quickly finish your shower and head to class, on the way you ask yourself why you didn't masturbate more, you are still shaken from the previous orgasm and you already want more. As you enter the class you feel your pussy getting moist again.
